Hello
DO you know if it is necessary that Dicom Images need to have Pixel Spacing into their metadata tags in order to be eligible for 3d reconstruction? I have several dicom images that do not have metadata, still they can be 3d visualized using some algorithms but cannot using others.
So my point is, Is PixelSpacing a required value for this purpose or not?

That depends on the modality. Some viewers/processors will assume the Pixel Spacing property to be [1 1 1] if it is missing, so that might be the reason some viewers do succeed.
